Ars spoke with the military’s chief orbital traffic cop—here’s what we learned

Agrawal was in the room, too. "I was on the crew that needed to count the pieces," he told Ars. "I didn’t know the significance of what was happening until after many years, but the Chinese had clearly changed the nature of the space environment." The 2007 anti-satellite test also clearly changed the trajectory of Agrawal's career. We present part of our discussion with Agrawal below, and we'll share the rest of the conversation tomorrow. The text has been lightly edited for brevity and clarity

F1 in Belgium: The best racetrack in the world

The Belgian tourist board provided nothing to this article, the writer just really really loves Spa-Francorchamps. Ars does not accept paid editorial content. Formula 1 made its annual stop at Spa-Francorchamps, the historic track that winds its way through the hills and trees of the Ardennes. I’ll admit, I’d been waiting for this one; in fact, I’ve become somewhat of a Spa bore, having fallen in love with the place all over again a few weeks ago while attending the Crowdstrike 24-hour GT3 race

This new AIO cooler packs more displays than your entire setup

Because, Why Not: There has been a growing trend among many PC builders recently: in-case displays. Not only have these screens been getting bigger and more advanced, but some people find that one just isn't enough. That's where Chinese firm Jonsbo comes in. The company's new AIO cooler series packs a bewildering four customizable LCDs. Jonsbo's TF3-360SC series initially looks like a typical AIO cooler with a 3.5-inch 640 x 480 screen built into the pump block – a design we've seen many times

Scattered Spider is running a VMware ESXi hacking spree

Scattered Spider hackers have been aggressively targeting virtualized environments by attacking VMware ESXi hypervisors at U.S. companies in the retail, airline, transportation, and insurance sectors. According to the Google Threat Intelligence Group (GITG), the attackers keep employing their usual tactics that do not include vulnerability exploits but rely on perfectly executed social engineering "to bypass even mature security programs." A Scattered Spider attack The researchers say that th

This 16-inch Acer is a full-package value pick I'd happily replace my main laptop with

Acer Swift 16 AI ZDNET's key takeaways The Acer Swift 16 AI is available now starting at $1,250. Its 16-inch OLED display, well-designed lightweight form, and marathon battery work together to create a laptop that feels more premium than its price would suggest. Its speakers, however, leave much to be desired, and it has its fair share of bloatware. $1,299 at Walmart $1,249.99 at Best Buy more buying choices Acer's Swift 16 AI is a thin and light laptop with a gorgeous OLED display, nice full

These Are the First FireSat Images for Finding Wildfires from Space

At Google I/O in May, Google revealed that it's working with the Earth Fire Alliance on FireSat, a program that combines new high-resolution satellites with AI analysis to pinpoint wildfires in their earliest stages and help responders knock them down before they grow. This week the alliance released the first images captured by the initial satellite, showing how fires as small as 5-by-5 meters -- about the size of a classroom -- can be detected from space. FireSat identified this small roadsid

Formal specs as sets of behaviors

Amazon’s recent announcement of their spec-driven AI tool, Kiro, inspired me to write a blog post on a completely unrelated topic: formal specifications. In particular, I wanted to write about how a formal specification is different from a traditional program. It took a while for this idea to really click in my own head, and I wanted to motivate some intuition here. In particular, there have been a number of formal specification tools that have been developed in recent years which use programmi

‘Wizard of Oz’ blown up by AI for giant Sphere screen

In Brief The massive Las Vegas venue known as Sphere will be screening its first classic movie, “The Wizard of Oz,” starting on August 28. And as detailed in a segment on CBS Sunday Morning, this isn’t just a matter of taking the existing movie and projecting it on Sphere’s 160,000 square foot, wraparound LED screen. Instead, Sphere Entertainment CEO James Dolan said a 2,000-person team is creating a new experience. That includes using AI to both increase the resolution of the existing film an

Return of wolves to Yellowstone has led to a surge in aspen trees

Wolves were reintroduced to Yellowstone in 1995, over 60 years after their eradication from the national park. Yellowstone's wolves are helping a new generation of young aspen trees to grow tall and join the forest canopy — the first new generation of such trees in Yellowstone's northern range in 80 years. Gray wolves (Canis lupus) had disappeared from Yellowstone National Park by 1930 following extensive habitat loss, human hunting and government eradication programs. Without these top predat

Chemical process produces critical battery metals with no waste

Olivine is a rather unassuming rock. Olive brown to yellow green in color, this hard yet brittle mineral is thought to be the most abundant in Earth’s upper mantle. Chemically, olivine is magnesium iron silicate, though it contains other elements too. Economically, it’s close to worthless. Its limited industrial utility stretches to gemstones, metalworking, ceramics, and occasionally, as a gravel for road construction. At some mining sites, olivine is a waste product, stored in piles on the surf

Personal aviation is about to get interesting (2023)

Aviation is a poster child for economic stagnation. Yes, airline travel has gotten cheaper and safer—great. But every other aspect of aviation has struggled or even regressed. As I’ve noted many times, we had supersonic travel across the Atlantic from 1976 to 2003. Today, not even the world’s richest travelers can fly that fast. Another part of aviation that has suffered over the last half-century is general aviation, particularly its low-end segment, personal aviation, in which people fly them

Algorithm for simulating phosphor persistence of analog oscilloscopes

Background to phosphor displays and analog oscilloscopes For all of you that have used analog oscilloscopes or other equipment with a phosphor display knows how beautiful the image can be from such displays. The color grading, which naturally occurs due to the persistence in the glow from the phosphor, also acts as a useful measurement on the signal integrity, such as how much noise there is and the shape/modulation of the underlying signal. Photograph of the display on a COS6100A analog oscil

‘Magic: The Gathering’ Swung Into the Spider-Verse at Comic-Con

We’re on the cusp of the release of Magic: The Gathering’s next major set, Edge of Eternities, next week, but that didn’t stop Wizards of the Coast from swinging into San Diego Comic-Con to show off its next big crossover: Spider-Man. And in our first major glimpse at what to expect from the set, we got treated to a whole spider-verse of new cards—and, of course, some very nifty comic book-themed variants to get your wallet’s spidey senses tingling. It’s no surprise that transforming cards are

Scientists Find Evidence That Original Life on Earth Was Assembled From Material in Space

The molecules that form the building blocks to life may be far more common in space than once thought, according to researchers from the Max Planck Institute. Their work, published in The Astrophysical Journal, reports the detection of over a dozen types of complex organic molecules swimming closely around a protostar in the constellation Orion, suggesting that the chemicals can survive the violent processes that give birth to stars and thus may abound in space, instead of having to wait for a

5G promised a revolution, but here’s what we actually got

Robert Triggs / Android Authority Depending on where you live, you’ve likely had 5G in your pocket for at least a couple of years — or possibly close to half a decade. In any case, the wireless tech has certainly been around long enough to have had time to accomplish the numerous lofty promises that CEOs piped up to upsell us, which included everything from rejuvenating retail to traffic lights pushing updates to your car. While some of those promises might have come to pass, quite a lot of th

New Speed Test Results Reveal the Fastest Internet Service Provider in the US

There's been a lot of talk about internet speed lately. From various company taglines -- "Don't take slow for an answer" -- to the latest news about Japan's internet data transmission record, it's all about the speed. This week, Ookla released its Speedtest Connectivity Report for the first six months of 2025, and AT&T Fiber topped the list as the country's fastest fixed internet service provider. (Ookla is owned by the same parent company as CNET, Ziff Davis.) What does that mean? Does it tell

Intel is spinning off its Network and Edge group

In Brief Intel continues to streamline its business. The company plans to spin off its Network and Edge group, which is responsible for making chips for the telecom industry, as originally reported by CRN. Intel will be an anchor investor in the stand-alone business and will seek outside capital. Intel was rumored to be looking for a buyer for its Network and Edge group in May. This business produced $5.8 billion in revenue in 2024. This strategy seems similar to the company’s decision to sp

The Tabs vs. Spaces war is over, and spaces have emerged victorious

The great indentation war is over and it seems like we have a clear winner. Every now and then, while exploring a new programming language, I inevitably stumble upon a heated debate, often buried deep in a GitHub issue thread, where contributors are passionately arguing over whether the language’s formatter should default to tabs or spaces. Over the past few months, as I’ve been immersing myself in Zig, I encountered one such discussion. It got me thinking: After decades of writing code, how i

Elon Musk Swipes Back at Trump After Apparent Peace Offering

Yesterday, President Trump seemed to offer an olive branch to his former “first buddy,” Elon Musk, amidst their ongoing spat. In a post made to Truth Social, Trump claimed that he didn’t wish any harm on Elon or his businesses. “Everyone is stating that I will destroy Elon’s companies by taking away some, if not all, of the large-scale subsidies he receives from the U.S. Government. This is not so! I want Elon, and all businesses within our Country, to THRIVE, in fact, THRIVE like never before!”

Google took a month to shut down Catwatchful, a phone spyware operation hosted on its servers

Google has suspended the account of phone surveillance operator Catwatchful, which was using the tech giant’s servers to host and operate the monitoring software. Google’s move to shut down the spyware operation comes a month after TechCrunch alerted the technology giant the operator was hosting the operation on Firebase, one of Google’s developer platforms. Catwatchful relied on Firebase to host and store vast amounts of data stolen from thousands of phones compromised by its spyware. “We’ve

Samsung Galaxy Z Flip 7 review: More screen, more battery but something's missing

Samsung’s annual foldable refresh includes a trio of devices this year. While the Z Fold 7 comes with a top-tier processor and cameras, the Z Flip 7 carries over many technical details from its predecessor. In fact, the most significant upgrade this year is a more expansive front display, or Flex Window, as the company prefers to call it. Samsung has also, somehow, added an even bigger battery to a slimmer foldable, which is technically impressive. However, the company made minimal software add
